Any chance you might add an (optional) way to get analytical derivatives for the noise result?
Derivatives are handy because they tell you the ”slope” of the noise, which is incredibly useful for u…

This will not be easy and it will take times.
Right now, as time is limited, I'm thinking about doing one level at a time.

It would be nice if in the world DSL we had access to the derivative of the noise function.
This would allow one to distinguish between, say, the eastern shore (to place beaches) and western shore (t…

I'm wondering why in the budget optimizer analytical gradients are not used instead of finite difference since they are faster and more accurate. With large dataset finite difference doesn't seem feas…

Right now we only provide the PengRobinson76 EoS both with analytical and automatic derivatives. We need to extend this more to more models

Hello,I have a question about QR and calculation of partial derivatives. Say I have a input A(x), it is a m×n matrix and x={x1,x2,x3,...xn} is argument. Q is the orthonormal basis of the A(x), namely …

Good idea for checking analytical derivatives to high accuracy.
* also get an estimation of the numerical error

We could add a helper function that computes first and second derivatives for only one element of a partition of the parameter space.
We have several applications where we can comput…

Hi,
This is somewhat of an open issue. An eigenvalue decomposition is necessary for line mixing ECS computations to be effective. This is done. We also need partial derivatives w.r.t. user input…
